Table 3 Cervical spondylotic angle (CSA) score results

Time	1 day pre-op	3 days post-op^a	3 months post-op^b	12 months post-op^c
CSA score	13.69 ± 3.09	13.20 ± 2.94	13.73 ± 2.96	13.78 ± 3.02

CSA scores are presented as mean number ± standard deviation (x ̅±s, n = 32). “^{a b c}” respectively represents the comparison between 3 days, 3 months and 12 months post-op and pre-op. Analysis using paired t-tests showed that P_a = 0.001、P_b = 0.724、P_c = 0.561, indicating significant differences were observed on 3 days postoperative, but there was no statistical significance on 3 months and 12 months postoperative
